   6  * There seems to be no way of detecting this automatically from user
   7  * space, so 64 bit architectures should override this in their
   8  * bitsperlong.h. In particular, an architecture that supports
   9  * both 32 and 64 bit user space must not rely on CONFIG_64BIT
  10  * to decide it, but rather check a compiler provided macro.
